In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "electrically connected" with another part in between . Also, when an element is referred to as " comprising ", it means that it can include other elements as well, without departing from the other elements unless specifically stated otherwise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a cloud system for printing or copying content stored in a user terminal according to an exemplary embodiment of the present invention to a display screen of a TV.

1, the cloud system 1 includes a cloud 10, an electronic device 20, and a display device 30. [ On the cloud system 1, the electronic device 20 and the display device 30 can be connected via the cloud 10. However, the cloud system 1 of FIG. 1 may include other general components not shown in FIG. 1, in addition to the above-described components.

The cloud 10 on the cloud system 1 may correspond to a server that performs various content processing such as storage, rendering, and transmission of the content. The cloud 10 may be implemented as a single server device or as a collection of server devices in which several server devices are logically connected.

The electronic device 20 on the cloud system 1 may correspond to, for example, a smart phone having mobile communication functions. That is, the electronic device 20 may correspond to a device that performs various functions to listen to content, store content, and transmit / receive content to other devices while the user is carrying it. Although the electronic device 20 is illustrated in FIG. 1 as being a smartphone, the electronic device 20 may be other types of devices such as a tablet device, a wearable watch device, a wearable eyeglass device, and the like. In addition, the cloud system 1 may include a computer such as a PC, a notebook computer, etc. instead of the electronic device 20 as a device for listening to the content, storing the content, and transmitting / receiving the content to other devices.

The display device 30 on the cloud system 1 may correspond to, for example, a TV. When the display device 30 corresponds to a TV, the display device 30 can function as a device for viewing a broadcast program received from a broadcaster. In addition, the display device 30 may include a function of displaying content on the Internet, a function of surfing the web, and the like, in addition to a broadcast program, such as recently released smart TV. 1, the display device 30 is exemplified as a TV, but not limited thereto, the display device 30 may include various devices having a display screen, for example, a smart phone, a tablet device, a PC, A notebook, a large format display (LFD), and the like.

That is, as shown in Fig. 1, the electronic device 20 on the cloud system 1 does not necessarily have to be a smart phone, and the display device 30 on the cloud system 1 does not necessarily have to be a TV. In other words, the roles of the electronic device 20 and the display device 30 on the cloud system 1 can be performed by various devices of other kinds not shown in Fig. 1 in addition to smart phones and TVs.

The electronic device 20 may store photographs taken by a camera module included in the electronic device 20, collected via the Internet, or received from another user. In addition, the electronic device 20 can display the pictures 1010 and 1020 to the user of the electronic device 20 through the display screen. According to the cloud system 1 of the present embodiment, the user can print or copy the photographs 1010 and 1020 stored in the electronic device 20 to the display screen of the display device 30. In other words, the electronic device 20 can output the photograph stored in the electronic device 20 to the display screen of the display device 30. [

More specifically, the electronic device 20 transmits the photo files associated with the photos 1010 and 1020 stored in the electronic device 20 to the cloud 10. The cloud 10 converts the file format of the received photo file into a predetermined document file format that the display device 30 can display. That is, the cloud 10 converts the photo file into a photo file of a specific document file format that can be displayed by the display device 30. [ The specific file format that the cloud 10 transforms may include, for example, a Portable Document Format (PDF) or an XPS document file.

The cloud 10 transmits the photo files 1010 and 1020 to the display device 30. The display device 30 can complete the operation of the display copy requested from the electronic device 20 by displaying the received photo files 1010 and 1020 on the display screen.

In this embodiment, the term "display copy" refers to the content stored in any source device (e.g., electronic device 20) as the display of at least one target device (e.g., display device 30) It is a function to display on the screen and can be widely defined. More specifically defined for the term "display copy ", a" display copy "means that, when a source device (electronic device 20) transmits content to the cloud 10, the cloud 10 sends the received content (E.g., the display device 30) is rendered / transformed from the cloud 10 into a predetermined document file format that can be displayed by the target device (the display device 30) Quot; may refer to a series of cloud service processes that receive content in a file format and display the content on a display screen. Further, the term "display copy" may also be defined to include the functions and operations of the various cloud services to be processed in the cloud system 1, which will be described below.

In other words, the display copy is displayed through the rendering / conversion process of the content by involvement of the cloud 10 in conformity with the display format of the target device. In this case, the content is directly transferred from the source device to the target device, Is simply displayed.

The display copy also differs from display mirroring technology. In general, display mirroring is different from the concept of the display copy of the present embodiment, since it means only a technology for controlling the display of the same screen like a mirror between different display devices.

The display copy is defined as a function to output the content stored in the source device (electronic device 20) to the content 1030 and 1040 on the display screen of the target device (display device 30), as described above . Thus, the display copy can be understood to be a paradigm different from hard copy or soft copy.

2 is a view for explaining the types of electronic devices and the types of display devices that may exist on the cloud system.

Referring to FIG. 2, electronic devices 500 and target devices 600 on the cloud system 1 may be interconnected via a cloud 10.

The electronic devices 500 may include an electronic device 20 (smart phone), an electronic device 51 (tablet device), a PC 52, a notebook 53, an image forming device 54, and the like. All of the electronic devices 500 are devices having various functions for controlling content such as a function of storing contents such as photographs, moving pictures, document files, a function of editing contents, a function of transmitting contents to other devices Various other devices as well as the electronic device 20 (smart phone), the electronic device 51 (tablet device), the PC 52, the notebook 53, the image forming device 54 shown in Fig. 3 .

The target devices 600 include an electronic device 21 (smart phone), a display device 30 (TV), an image forming device 55, an electronic device 62 (tablet device), a notebook computer 63, (64), and the like. All of the target devices 600 are devices having a display screen, and have a function of displaying contents such as photographs, moving pictures, document files, and the like. However, the target devices 600 include the electronic device 21 (smart phone), the display device 30 (TV), the display device 61 (LFD), the electronic device 62 ), The notebook computer 63, the PC 64, and various other devices.

3 is a diagram illustrating an example of utilizing the functionality of a display copy at remote offices in accordance with one embodiment.

3, it is assumed that the user A who uses the electronic device 20 works in the Seoul office and the user B who uses the display device 30 works in the New York office.

In the Seoul office, the user A can store the WORD document 3001 related to the minutes on the electronic device 20. [ Then, user A may wish to display a WORD document 3004 in user B who works in New York office. Here, the user A may desire to be displayed on the display device 30 used by the user B, rather than merely transmitting the WORD document 3001 in the user B. That is, the user A may desire to display the WORD document 3001 stored in the electronic device 20 on the display device 30 used by the user B. [ This may be the case where, for example, a user A who works in a Seoul office and a user B who works in a New York office proceed in a video conference in real time.

The electronic device 20 transmits the document file 3002 ("minutes.doc") corresponding to the stored WORD document 3001 to the cloud 10.

The cloud 10 renders / converts the document file 3002 ("minutes.doc") into a document format, such as PDF or XPS, of a file that the display device 30 can display. In general, the display device 30 such as a TV can not display the contents of each page of a document file such as a MicroSoft Word file, a MicroSoft PowerPoint file, etc., so that rendering / conversion processing by the cloud 10 is required . Thus, in the present invention, a document can be converted into a general document file format. The document format can be read or printed by the operating system, and can include a standard file format of the digital document in which the font, image, graphics, and document type of the original document are maintained.

The cloud 10 transmits the document file 3003 ("minutes.pdf") generated by the rendering / conversion to the display device 30.

The display device 30 displays each page 3004 of the document file 3003 ("minutes.pdf") received via the display screen. Thus, the user B can view and share the WORD document 230 stored in the electronic device 20 by the display copy requested by the user A on the display screen. Also, since the converted file 3003 retains the font, image, graphic, and document type of the original document, the user B selects the desired word (s) in each page 3004 of the document file 3003 Or search for photos.

3, a display copy function is performed between a remote Seoul office and a New York office. However, if the electronic device 20 and the display device 30 are connected to each other via the cloud 10, The function of the display copy as described above can be performed.

4 is a diagram illustrating a detailed hardware configuration of a cloud according to an exemplary embodiment.

4, the cloud 10 may include an API server 11, a rendering server 12, a control server 13, an authentication server 14, and a storage server 15. However, the cloud 10 of FIG. 4 may be implemented by additionally including other components not shown in FIG. 4, in addition to the above-described components.

The implementation of the cloud 10 may vary. For example, if at least one of the API server 11, the rendering server 12, the control server 13, the authentication server 14, and the storage server 15 is a physically separate server device, ) Can be implemented by building a framework for virtualizing independent server devices into one server device and logically connecting each other. Alternatively, the cloud 10 is implemented as a single server device, and the API server 11, the rendering server 12, the control server 13, the authentication server 14, and the storage server 15 may be implemented as a software module or a hardware module Lt; RTI ID = 0.0 > a < / RTI > server device. That is, the implementation of the cloud 10 is not limited by any one.

The API server 11 is a server that acts as a gateway to allow a device existing outside the cloud 10 to access the cloud 10. The API server 11 may be a REST API (Rewritable State Transfer Application Programming Interface) module, a RESTful API modules, and the like, but are not limited thereto.

The API server 11 is also a standardized protocol server for transferring messages between different devices (for example, the electronic device 20 and the display device 30) via the cloud 10. For example, The API server 11 may be implemented as an open protocol based server, such as an Extensible Messaging and Presence Protocol (XMPP) server, but may be implemented as a server using other types of protocols.

Rendering server 12 renders the content sent from the source device (e.g., electronic device 20) to fit the display format of the target device (e.g., display device 20). That is, the rendering server 140 may correspond to a rendering engine that renders / transforms the content. As described above, the rendering server 12 may, for example, render / transform a WORD file ("minutes.doc") sent from the electronic device 20 to a general purpose document file . Described in detail, a printer driver is generally a language that can interpret a document file (for example, a doc file, a ppt file), an image file (for example, a JPG file or a GIF file) (PDL), but the rendering server 12 can display the content on the display device 30 and render / convert the content into a document file format that can maintain the original format.

The rendering server 12 may include a plurality of rendering modules corresponding to the format of the content file. The rendering server 12 may include a plurality of rendering modules corresponding to all file formats in which the content can be represented, such as an image file format, a document file format, a moving image file format, and the like. The rendering server 12 may convert the received content into a predetermined document format content using a rendering module corresponding to the file format of the content. The document format is a standard file format for digital documents that can be read or printed by the operating system and retains the font, image, graphics, and document format of the original document. For example, the document format is pdf or XPS format.

The control server 13 controls the functions and operations of the other servers in the cloud 10, namely, the API server 11, the rendering server 12, the authentication server 14 and the storage server 15, respectively. On the other hand, when the application is executed on the electronic device 20 and the display device 30 shown in Fig. 1 or the like, the control server 13 transmits information processed in the chat room, for example, a transmission / reception of a chat message, And so on.

The authentication server 14 is a server for authenticating a user connected to the cloud 10. For example, when authentication is required to transmit the content of the document file format to the display device 30, it can be authenticated through the authentication server. The authentication server 14 may be replaced with an external authentication server (LDAP, etc.).

The storage server 15 stores various information processed in the cloud 10, stores the content transmitted from the source device (the electronic device 20), or stores the rendered content.

On the other hand, the cloud 10 can be implemented as Iaas (Infrastructure as a Services) such as Amazon EC2 (Elastic Compute Cloud) and Amazon S3 (Simple Storage Service) provided by AWS (Amazon Web Services). Alternatively, the cloud 10 may be implemented in a form having a cloud architecture that is independently built for B2B (Business to Business) without depending on an Iaas company or a Platform as a Services (Paas) provider. That is, the architecture implementation of the cloud 10 is not limited by any one.

5 is a view for explaining a detailed operation of a cloud for performing a function of a display copy in a cloud system according to an embodiment.

The electronic device 20 transmits the various identification information of the display device 30 and the unique name of the display device 30 to the cloud 10 using the application to transmit the display device 30 to the cloud 10. [ . Here, the identification information of the display device 30 may include a MAC address, a serial number, an IP address, and the like of the display device 30. The unique name of the display device 30 may be a name May be a randomly set nickname. The electronic device 20 can also use the application to send the login information of the user of the electronic device 20 to the cloud 10 (web address (URL) of the API server 11). Thereafter, the electronic device 20 can log in to the cloud 10 using the user's login information.

The display device 30 can also receive various control information for displaying the content from the cloud 10 (control server 13) using the application. For example, the control information may include information about the display styles (display time, screen switching interval, etc.) of the content, the page number of the content to be displayed, and the like.

5, the content stored in the electronic device 20 can be displayed on the display screen of the display device 30 via the cloud 10. [

In step 501, the electronic device 20 designates the content to be requested and a display device to transmit the display copy to the API server 11. That is, the electronic device 20 shares the content with the cloud 10.

In step 502, the API server 11 transmits the content transmitted from the electronic device 20 to the control server 13. That is, the API server 11 shares the content with the control server 13.

In step 503, the control server 13 may control the storage server 15 so that the transferred content is stored in the storage server 15. [

In step 504, the control server 13 generates an instruction of a rendering operation for the content whose display copy is requested, and transmits an instruction of the rendering operation to the rendering server 12. Here, the rendering operation is for rendering / converting the file format of the content into a document file format that can be displayed on the display device 30. The rendering server 12 stores the received rendering job in a queue.

In step 505, the rendering server 12 requests the storage server 15 to transfer the content to be rendered, in the order of processing the rendering job stored in the queue.

In step 506, the storage server 15 transmits the content to be rendered to the rendering server 12.

In step 507, the rendering server 12 renders / converts the file format of the content transmitted from the electronic device 20 into a document file format that can be displayed on the display device 30. For example, you can render doc, pptx, xlsx, and other files to a file in the format pdf, xps, and so on.

In step 508, when the rendering is completed, the rendering server 12 stores the rendered content (general-purpose document files or compressed files of general-purpose document files) in the storage server 15.

In step 509, the API server 11 may receive content request and authentication information from the display device 30 specified by the electronic device 20. [ Alternatively, according to another embodiment, the API server 11 can request content from the display device while requesting authentication information.

In step 510, the API server 11 may transmit a request to the control server 13 to confirm the authentication information of the display device 30. [

In step 511, the control server 13 may request the authentication server 14 to confirm the authentication information of the display device 30. [

In step 512, the authentication server 14 can perform authentication of the display device 30 by comparing the authentication information previously stored with the authentication information received from the display device 30. When the authentication is confirmed, the authentication server 14 May transmit to the control server 13 that the authentication information has been confirmed.

In step 513, the control server 13 may request the storage server 15 to transmit the rendered content.

In step 514, the storage server 15 may transmit the rendered content to the display device 30. At this time, the storage server 15 can provide the storage device 15 with a storage directory, for example, a web address (URL), to which the application of the display device 30 can access the display device 30. Then, the display device 30 can access the web address (URL) and download the rendered content.

In step 515, the display device 30 is controlled such that the content requested to be displayed on the display screen of the display device 30 is displayed.
